Hi Stefan,
thanks for your answer. I think the deprecated option is still supported and I
found something else - I will update to the new option though. On the ceph
side, I see in the log now:
client session with non-allowable root '/' denied (client.31382084
192.168.48.135:0/2576875769)
It looks like the path option of vfs_ceph is not passed on correctly. I did
neither try nor allow to mount the root itself, but a sub-directory. It looks
like one of the combinations I tested works, but the path into the ceph fs is
not used. The option I use is:
path = /shares/FOLDER-NAME
and this should show up in the client session as root '/shares/FOLDER-NAME'.
Starts looking like a bug in vfs_ceph.c .
Best regards,

In ceph/src/common/options.cc I found this:
Option("client_fs", Option::TYPE_STR, Option::LEVEL_ADVANCED)
.set_flag(Option::FLAG_STARTUP)
.set_default("")
.set_description("CephFS file system name to mount")
.set_long_description("Use this with ceph-fuse, or with any process "
"that uses libcephfs. Programs using libcephfs may also pass "
"the filesystem name into mount(), which will override this
setting. "
"If no filesystem name is given in mount() or this setting, the
default "
"filesystem will be mounted (usually the first created)."),
/* Alias for client_fs. Deprecated */
Option("client_mds_namespace", Option::TYPE_STR, Option::LEVEL_DEV)
.set_flag(Option::FLAG_STARTUP)
.set_default(""),
So the client_mds_namespace is deprecated, and maybe even removed? Does
it work if you specify "client_fs"?
